6-2: Slope Intercept Form***The most important equation you’ll learn in

all of Algebra!!! So, pay attention! ;)

LINEAR FUNCTION/EQUATION: a function whose graph is a line.

PARENT FUNCTION: The simplest equation of a function. The equation y=x or f(x)=x is the LINEAR PARENT FUNCTION

First… the Vocabulary

Y=mx+b m = slope b = y-intercept

Y-INTERCEPT: the y-coordinate of the point where a line crosses the y-axis

SLOPE INTERCEPT FORM

Identify the slope and y-intercept.What will the graphs look like?y=3x+1y=1/2x – 5y=-2x+4y=xY= 2x

Some examples

Now, it’s your turn to graph these equations.Draw a large coordinate graph (using a ruler) in your notebooks. We’ll walk through each one slowly.y=3x+1y=1/2x – 5y=-2x+4y=xY= 2x
